BANDANNA. 91 Sixteen engines similar to the above, each possessing the power of pressing withseveral huncIVed tons, are arranged in one line, in subdivisions of four; the spaces. between each subdivision serving as passages to allow the workmen to go readilyirom the front to the back of the presses. Each occupies twenty-five feet, so that thetotal length of the apartment is 100 feet. To each press is attached a pair of patterns in lead, (or plates, as they are called,) themanner of forming which will be described in the sequel. One of these plates is fixedto the upper block of the press. This block is so contrived, that it rests upon a kind ofuniversal joint, which enables this plate to apply more exactly to the under fellow-plate. The latter sits on the moveable part of the press, commonly called the this is forced up, the two patterns close on each other very nicely, by means ofthe guide-pins at the corners, which are fitted with the utmost care. The power which impels this great hydrostatic range is placed in a separate apart-ment, call
